Do you ever think about the younger version of yourself and wonder if they are still a part of you or if you totally replaced them?

I was thinking of this when I was reading “the little prince” a book with themes about childhood.

It made me question if the child version of myself is still me, if he is a part of me, or if the current me replaced him.

Also it takes 5 years for every atom in your body to be replaced so from a materialist perspective you replace your younger self.
